Excessive gingival display is an esthetic issue that is commonly managed by different procedures. Lip repositioning is a modality to address concerns of affected patients. The aim of this review was to investigate the scientific evidence on outcomes and long-term stability of lip repositioning surgery with or without myotomy. The electronic search was conducted in three databases: MEDLINE, Embase, and the Cochrane Library up to October 2019. No publication status, language, or time restrictions were applied. The electronic search was complemented by a manual search of the reference lists. Three hundred thirty-eight studies were screened by title, and 16 articles remained for data extraction. The included studies assessed the lip repositioning procedure in 144 patients aged between 15-59 years (134 females and 10 males). Based on the available data, lip repositioning with myotomy/muscle containment can be a successful treatment for minor discrepancies in gingival display in selected cases. However, further well-organized controlled clinical trials are recommended to derive a conclusion about the long-term stability compared with other alternatives.
牙龈过度外露是一个美学问题，通常通过不同的手术方法来处理。唇部重新定位是解决受影响患者问题的一种方式。本综述的目的是研究有无肌切开术的唇部重新定位手术的结果和长期稳定性的科学证据。截至2019年10月，在三个数据库（MEDLINE、Embase和Cochrane图书馆）中进行了电子检索。未应用出版状态、语言或时间限制。电子检索辅以对参考文献列表的手动检索。通过标题筛选了338项研究，16篇文章留作数据提取之用。纳入的研究评估了144例年龄在15至59岁之间的患者（134名女性和10名男性）的唇部重新定位手术。根据现有数据，在选定病例中，采用肌切开术/肌肉封闭的唇部重新定位可能是治疗牙龈外露轻微差异的成功方法。然而，建议进一步开展组织良好的对照临床试验，以便与其他替代方法相比得出关于长期稳定性的结论。
